BoundedAttributes validation is too strict for logs

[xrmx]

Describe your environment

OS: (e.g, Ubuntu)
Python version: (e.g., Python 3.8.10)
SDK version: (e.g., 1.25.0) 1.31.1
API version: (e.g., 1.25.0) 1.31.1

What happened?

When we create LogRecord instances we convert the attributes to instances of BoundedAttributes.
BoundedAttributes validates values to be one of bool, str, bytes, int, float when in log we should support AnyValue as stated by the spec https://opentelemetry.io/docs/specs/otel/logs/data-model/#field-attributes

Steps to Reproduce

Send a dict as attribute value

Expected Result

Dict attribute is serialized

Actual Result

Warning is raised instead Invalid type dict for attribute 'request_header' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
